Delete data row from data table

Help

Hi there @1vivek12,
You can do the following:

Assign – dtMyDataTable = dtMyDataTable.AsEnumerable.GroupBy(Function (x) x.Item("Sector_ID")).Select(Function (i) i.First).CopyToDataTable

This will return the first rows with unique values in the column “Sector_ID”.

Thanks,
Josh

There is no need to loop and delete.i think below should do the same.give a try.

Data = Data.Select(“[Status] <> '”+Policy_num+“'”).CopyToDataTable

Hey @Aditipatil

It will just create a new datatable with results where no match will be there. so you can use that datatable for your further operation.
if you wanna delete rows then there is post already exist by me, so search it :slight_smile:

Hey @Aditipatil

Yes you can overwrite the results in the same excel.

just use Write Range ACtivitiy with blank range on the same excel file.

Their is problem with your assignment or something… check your datatable content first before writing with output datatable activity in studio: :slight_smile:

Yeas, so at the moment this is what I have. The Output looks something like:
7
3
6
4
10
5
etc…

But I would like to delete all odd numbers. In this case the ouytput would be like:
6
4
10
2
etc… (So only even numbers)

Hi @narayan_shrawagi,

Datatable->Dt1
Datatable->D2
User for each row activity ->Dt2

use Assign activity
Dt1=Dt1.Select("empid <> '"+row("contractorid ").Tostring()+"'").CopyToDataTable()

Arivu

hey @narayan_shrawagi

If you will read all post in this thread above you can get your approach and idea.

you can instead of delete much rows take only those data which is needful for next step so just check your idea from above existing post and get the actual context and if still face any prob let me know.

Solution Without Usign for each:

Datatable result = DT1.AsEnumerable().Where(function(row) Not DT2.AsEnumerable().Select(function(r) r.Field(Of Int32)("Contractorid")).Any(function(x) x = row.Field(Of Int32)("empid"))).CopyToDataTable()

try while loop instead of for loop if you want to use Remove Datarow
